Old Tagging rules "attribute unavailable" in Mavericks

Hi,
I've had a rule in Hazel which moved files from one folder to another if
* the file got tagged (Openmeta) and
* the tagging date was older than a week.
After upgrading to Mavericks the rules in Hazel show "attribute unavailable" and do not work anymore. Is there any possibility to bring these rules back (or apply them to the Mavericks tagging system)? In fact, all OpenMeta tagging rules show "attribute unavailable".
Unfortunately I created these rules a long time ago and have no clue anymore how I did it.
I'm on Mavericks (german language) with Hazel 3.2.1 (build 1049).
Thanks.
